EFFECTS OF NINTENDO WII FIT BALANCE BOARD VIRTUAL REALITY GAMES IN IMPROVING BILATERAL COORDINATION OF UPPER LIMB IN INDIVIDUALS WITH ACUTE STROKE -A PILOT STUDY

Abstract

Background: Stroke is a leading cause of disability worldwide and often results in impaired upper limb function and reduced bilateral coordination, which can limit independence in daily activities. Virtual reality–based rehabilitation has gained attention as an innovative approach that enhances patient engagement and promotes repetitive, task-oriented training. The Nintendo Wii Fit Balance Board offers interactive virtual reality games that may facilitate motor recovery and improve bilateral coordination in stroke rehabilitation. Objective: To investigate the effects of Nintendo Wii Fit Balance Board virtual reality games on improving bilateral coordination of the upper limb in individuals with acute stroke. Methods: A quasi-experimental pilot study was conducted among 20 individuals diagnosed with acute stroke. Participants were recruited based on predefined inclusion and exclusion criteria. All subjects received virtual reality training using Nintendo Wii Fit Balance Board games along with routine physiotherapy. The intervention was administered over a specified treatment period under supervision. Bilateral coordination of the upper limb was assessed before and after the intervention using ABILHAND Questionnaire. Pre- and post-intervention scores were analyzed to determine the effectiveness of the training. Results: Following the intervention, participants demonstrated a significant improvement in bilateral coordination of the upper limb compared to baseline scores. The mean preintervention score was  30.40 ± 1.24  and the mean post intervention score was  46.85 ± 1.11 . The interactive and task-specific nature of the Nintendo Wii Fit Balance Board games appeared to enhance motor learning, bilateral coordination, and patient motivation during rehabilitation. Conclusion: The findings of this pilot quasi-experimental study suggest that Nintendo Wii Fit Balance Board virtual reality games is  an effective adjunct in improving bilateral coordination of the upper limb in individuals with acute stroke. However, larger randomized controlled studies are recommended to further validate these results and support wider clinical application.
